A Kindle Paperwhite is roughly 17cm tall and 12cm wide — slim, but tall. The question is not width, it is height and closure.
Measure the Height, Not the Width
Most minis are too short. A hobo crossbody in a medium size takes a Kindle standing up. The crossbodies in a medium scale are the ereader sweet spot.
The Closure Test
A Kindle needs the bag to close over it — a bucket crossbody with a bit of give works better than a rigid flap. The bucket crossbodies forgive the extra height.
The Rule
Pro tip: ereader bags are about height, not width. Anything under 18cm tall will not close over a Kindle — go medium, and choose a shape with give.
Shop the medium crossbodies.
Frequently Asked Questions
Will a Kindle fit in a small crossbody?
Usually not — a Kindle Paperwhite is about 17cm tall and most small crossbodies are shorter. Choose a medium crossbody or a bucket shape with give.
What size bag do I need for a Kindle?
At least 18cm of interior height so the bag closes over the device, plus a little width margin for the bezel.
Is a tote better for an ereader?
Yes for travel — a tote carries the Kindle plus a water bottle and layers without the strap pressure of a loaded crossbody.
